Aquatic Weed Control by Grass Carp in Cool Water
Diploid grass carp have significantly controlled problem aquatic vegetation during a 3-year study in a northern Colorado irrigation canal where water temperatures ranged from 0 to 25?C....
Drought in Tennessee: Implications on Irrigation System Capacity
Recent droughts in Tennessee have led to a study of the required irrigation system capacity for the state. Data from 1951 through 1988 were analyzed for probabilities of precipitation...
Agricultural, Meteorologic, and Hydrologic Drought Relations: Applications to Irrigation and Water Supply Planning
Meteorologic and hydrologic factors can combine to significantly reduce crop yields, leading to an agricultural drought. Agricultural and hydrologic droughts affect a large segment of...
Locating and Sizing Air Release Valves on Irrigation Systems
This writing is directed to persons involved in irrigation systems and describes the usage of air release and vacuum valves. Principles described are applicable to many other piping systems,...
Estimating Impacts of Irrigation on Streamflow
This paper presents a method for estimating the impact of irrigation withdrawals on streamflows and shows the application of that method to the Kankakee River Basin of Illinois and Indiana....
Computer Control of Water Systems: Practical Considerations
Presented are some applications projects and procedures concerned with modeling and control of water supply and distribution systems. The work has resulted in the development of a suite...
Computer Support for TVA's Reservoir System Operations: Hardware
The current computer systems in use at TVA for hydrologic data collection and modeling are approaching ten years old. A study is in progress to determine the computer systems needed to...
Computer Support For TVA's Reservoir System Operations: Software
In the early 1980's, the Tennessee Valley Authority implemented its Water Resources Management Information (WATREMAIN) system to provide support for operation of its integrated multipurpose...
Development of the Hydro Optimization Management System at Alabama Power Company
Alabama Power Company is an electric utility serving most of Alabama with a generation mix of 65% coal, 18% nuclear, and 17% hydro. A total of 1682 MW hydro generation comes from 14 plants...
OMADSS?Operations and Maintenance Advanced Decision Support System
This paper presents a summary of the development of a prototype advanced decision-support system for operation and maintenance of dams and irrigation facilities. To set the development...
Multi-Purpose, Multi-Reservoir Simulation on a PC
The methodology and difficulties in converting a large, general purpose, mainframe, batch oriented computer program (for reservoir simulation) to work effectively in the PC environment...
An Emerging Application of Microcomputers in Water Control
Plans being developed at the Corps' Hydrologic Engineering Center propose a gradual transfer of water control support from minicomputers to a network of microcomputer workstations....
Role of Data Management in Water Control
The success of a system of software that must provide the water control user with current information, model analysis results, and forecasts of future behavior, is closely associated with...
Computer Program for Smoothing and Correcting Hourly Time Series Data
A FORTRAN computer program has been developed for the U.S. Army Corps of Engineers St. Louis District that automatically screens and corrects hourly time series data for gross errors and...
Development of the Hydrodata CD-ROM Data Storage System
To store and retrieve data from two of the USGS WATSTORE databases - the daily and peak values files - and the Summary of the Day file from the National Climatic Data Center, the authors...
Brief Description of Castor Software for Management of Reservoir Systems
The CASTOR group, started in 1984 at Ecole Polytechnique de Montreal (Canada), is a major software development project for an integrated CAD system related to hydro projects. Based on...
Input Processor Package for Water System Studies
An input processor package for a water distribution simulation model has been developed and field tested. This preprocessor enables users with little or no computer use experience to directly...
Simulation Model for Economic Irrigation Project Planning and Design
The principle design parameters considered are: water supply configurations (quantity, source and storage); shapes and sizes of the area to be served; on-farm irrigation techniques; cropping...
Optimal Allocation of Water for Irrigation and Hydropower
